JOHN S. KELLER, OF FLEMING-TON, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO GEORGEH. BARRETT, OF FLEMING'I'ON, PENNSYLVANIA.

PUNCH.

To all whom it may concern:

Be it known that I, JOHN S. KELLER, a v

V citizen of the United States, residing at Flemington, in the county of Clinton and State of Pennsylvania, have invented new and useful Improvements in Punches, of which the following is a specification.

This invention relates to hand implements for punching holes in leather or other material, and its object is-to provide a slmple and very eflicient tool of this kind, the parts whichmake up the same being so arranged that a powerful punching action is obtained with the expenditure of but little effort on the part of the operator, whereby the implement is rendered easy to operate.

The object stated is obtained by means of a novel combination and arrangement of elements to be hereinafter described and claimed, and in order that the same may be better understood, reference s had to the accompanying drawing forming a part of this specification.

In the drawing, Figure 1 is a plan view of the invention; Fig. 2 is a side elevation partly in section, and r Fig. 3 is an enlarged section on the line 33 of Fig. 2.

Referring specifically to the drawing, 5 denotes a lever handle fashioned at one end into a head 6 which is fitted with an anvil 7 toward which is movable a punch 8 which is carried by the outer end of a lever 9 pivoted at its inner end, as shown at 10 to the lever handle 5 intermediate the endsof the latter, the pivoted end of the lever 9 being forked as shown at 11 to straddle the lever handle.

To the lever handle 5 is pivotally connected a punch actuating lever handle 12 which is pivoted as shown at 13, to a forked member 14 integral with or fixed to, and extending from the lever handle 5. The outer end of the lever handle 12 is connected by a pair of links 15 to the die-carrying lever 9 adjacent to the outer end of the latter, as shown at 16, said links straddling the lever handle 5.

The lever handle 5 also carries a stripper for the work, the same being a yoke 17 extending laterally from a'shank 18 carried by the said lever handle and positioned between the links 15. The yoke straddles the copies of this patent may be obtained for five centseach, by addressing the Specification of Letters Patent.

Serial No. 245,260.

punch 8 and moves toward-the outer end thereof when the punch is retracted from the work, thereby forcing the work off the punch in an obvious manner.

The punch 8 is hollow and its rear end has a side opening 19 for discharging the punchings. I

In use, the sheet of leather or other material to be punched is placed on the anvil 7 and the two lever handles 5 and 12 are brought together, which forces the punch 8 through the material and makes a hole therein, the material being stripped off the punch by the. yoke 17 when the implement is opened up, and the punchings being discharged through the side opening 19. The compound leverage obtained by the arrangement of the several parts as hereinbefore described enables the punch to be forced through the material with but little effort, and the implement is therefore easy to operate. The implement will be made in various sizes according to the particular work it is to be used for.

I claim:

1. A punching implement comprising a lever handle, an anvil carried by said lever handle, a second lever handle and a lever pivoted to the first-mentioned lever handle, and located on opposite sides thereof, a punch carried by said lever and positioned opposite the anvil, and a link connection between the lever and the second-menti0ned lever handle, the latter being a lever of the first order, and the link being connected to the short arm thereof.

2. A punching implement comprising a lever handle, an anvil carried by said lever handle, a second lever handle extending alongside the other lever handle, with a pivotal connection therebetween, a lever pivoted at one end to the first-mentioned lever handle, a punch carried by the other end of the lever and positioned opposite the anvil, said lever and the second-mentioned lever handle being located on opposite sides of the first-mentioned lever handle, and a link connecting the second-mentionedlever handle to the aforesaid lever, the latter being a lever of the first order, and the link being connected to the short arm thereof.

, In testimony whereofI aflix my signature.

JOHN S. KELLER.
